Description

Technical Field

[0001] The utility model relates to the technical field of textile household products, in particular to a sofa seat cushion with a massage function. Background Art

[0002] Example of the prior art 1. Referring to the patent document CN207912461U, a combined sofa with a massage function is disclosed, which includes a long sofa and a reclining sofa. Both the long sofa and the reclining sofa include a base, a backrest, a cushion and a headrest. A seat cushion is provided on the base. The headrest includes a fixing plate and a pillow pad. Massage bumps are provided on the front surface of the cushion and the front surface of the headrest. Massage components are provided between the cushion and the backrest and between the pillow pad and the fixing plate. The massage component includes a massage plate, a polarized motor and a plurality of springs. The long sofa further includes a foot massager, which includes a drawer 1, a frame, massage wheels and a transmission motor. A switch 1 and a switch 2 for starting the transmission motor and the polarized motor are provided on the combined sofa. The utility model meets the needs of people to enjoy massage at home, can effectively relieve fatigue, and at the same time improves the utilization rate of the house space and the sofa itself. The sofa massage structure in Technical Example 1 is a fixed type and cannot be changed during use, so there are obvious defects. For example: 1. It cannot provide good massage effects for people of different heights and body shapes; 2. The contact points are single, and the pressure on some parts of the body caused by long-term leaning is relatively large, and there is no massage function for another part of the area, so discomfort is likely to occur.

[0003] Example of the prior art 2. Referring to the patent document CN103284870A, a three-dimensional massage cushion movement mechanism is provided, which includes a driving mechanism. The driving mechanism includes a motor, a gearbox, a gear, and a power output shaft; a bracket; an eccentric button, one end of which is fixedly connected to the power output shaft; a long arm shaft, one end of which is hinged to the other end of the eccentric button; a right long arm, the upper section of which is connected to the other end of the long arm shaft, and massage heads are provided on the upper section and the middle of the right long arm, and a hollow long groove is provided on the lower section of the right long arm; a massage wheel, which includes two upper end heads and a lower end head; a swing arm, one end of which is hinged to the lower end head of the massage wheel, and the turning point of the swing arm is hinged to the lower end of the right long arm; a linkage rod, one end of which is hinged to the other end of the swing arm; a sliding block, which is slidably embedded in the long groove; a support shaft, one end of which is connected to the sliding block, the middle of which is rotatably arranged on the bracket, and the other end of which is hinged to the other end of the linkage rod; a left long arm, which is symmetrical to the right long arm. The massage components of the present invention can achieve three-dimensional movement trajectories. The sofa massage structure in Technical Example 2 belongs to the electric type and can provide a more three-dimensional massage effect, but there are also certain shortcomings. For example: 1. The motor outputs unidirectionally, and the massage heads for the head and neck, waist, and back are connected to the same long arm. Therefore, it will be limited by the movement trajectory of the long arm, resulting in a single movement trajectory of the massage heads for the head and neck, waist, and back; 2. Since the massage heads for the head and neck, waist, and back are connected to the same long arm, there is a limitation in the spatial structure, that is, a unified and larger installation area (bracket) is required, which will cause the cushion area for the head and neck to decrease (because the head and neck are smaller in size than the waist and back), and when using, the head and neck cannot touch the cushion body, lacking effective support and reducing the comfort when contacting; 3. There is a lack of a structure for power supply. If the cushion is directly connected to the mains, since the mains voltage is relatively high, there are certain potential electrical safety hazards.

[0044] Embodiment 1

[0045] Referring to Figures 1 to 9 , a sofa seat cushion with a massage function, comprising:

[0046] A cushion body 1, which is internally provided with a first chamber 11 and a second chamber 12. The first chamber 11 corresponds to the head and neck area of the user, and the second chamber 12 corresponds to the back and waist area of the user;

[0047] A head and neck massage component 2, which is arranged in the first chamber 11;

[0048] A back and waist massage component 3, which is arranged in the second chamber 12;

[0049] A driving mechanism 4, which is arranged between the first chamber 11 and the second chamber 12. The driving mechanism 4 has a first power output shaft 41 and a second power output shaft 42. The first power output shaft 41 forms a transmission cooperation with the head and neck massage component 2, and the second power output shaft 42 forms a transmission cooperation with the back and waist massage component 3.

[0050] The above is the basic structural solution of the present utility model, and its working principle is: when the driving motor starts, it drives the head and neck massage component 2 in the first chamber 11 to move through the first power output shaft 41 to realize the massage function for the head and neck area of the user, and at the same time drives the back and waist massage component 3 in the second chamber 12 to move through the second power output shaft 42 to realize the massage function for the back and waist area of the user.

[0051] Therefore, compared with the prior art, the basic solution of the present utility model has at least the following advantages: First, a single driving mechanism 4 adopts a first power output shaft 41 and a second power output shaft 42 to achieve bidirectional output, thus having a dual power direction selection; Second, the cushion body 1 is respectively provided with a first chamber 11 and a second chamber 12 to provide relatively independent installation and operation spaces for the head and neck massage assembly 2 and the back massage assembly 3, and reduce the interference between the head and neck massage assembly 2 and the back massage assembly 3, enabling the two to operate independently, greatly reducing the failure rate and improving the use stability; Third, the width dimensions of the first chamber 11 and the second chamber 12 can be adjusted according to needs without being unified. Thus, a smaller first chamber 11 can enable the cushion body 1 to have more supporting fillers (such as sponges, etc.) on the periphery corresponding to the first chamber 11, thereby providing a better contact support effect for the head and neck.

[0052] Preferably, referring to Figure 3 , a transition chamber 13 is provided between the first chamber 11 and the second chamber 12, and the dual-output motor 44 is assembled in the transition chamber 13. The transition chamber 13 meets the installation space requirements of the dual-output motor 44 itself, and its position selection is more reasonable, while also meeting the requirements of the transmission position for bidirectional output.

[0053] It is worth mentioning that a receiving groove 121 is provided on the inner side of the second chamber 12, and the power supply 43 is embedded in the receiving groove 121. And a charging and discharging interface 14 is provided on the outer wall of the cushion body 1, and the charging and discharging interface 14 is electrically connected to the power supply 43. Through the limitation of the position of the power supply 43 and the setting of the charging and discharging interface 14, first, the power supply 43 can be replenished; second, it can discharge externally, and thus can charge external devices such as mobile phones and tablet computers; third, the power supply 43 is located in the receiving groove 121, having a relatively reliable installation space to prevent the operation of the head and neck massage assembly 2 and the back massage assembly 3 from touching or damaging the power supply 43.

[0054] Preferably, both the head and neck massage assembly 2 and the back massage assembly 3 have two groups and are symmetrically distributed left and right, thus having a larger massage area and improving the massage experience.

[0055] Embodiment Two

[0056] Referring to Figure 2 , Figure 4 , Figures 6 to 9 , on the basis of the structure of Embodiment One, the preferred solutions for each mechanism in the present utility model are as follows:

[0057] 1. Driving mechanism 4: including a power supply 43, a control circuit board 45 electrically connected to the power supply 43, a dual-output motor 44 electrically connected to the control circuit board 45, a first power output shaft 41, a second power output shaft 42, a first reduction gear plate 46 and a second reduction gear plate 47; the first power output shaft 41 and the second power output shaft 42 are respectively connected to the upper and lower ends of the dual-output motor 44; the first power output shaft 41 forms a transmission match with the head and neck massage component 2 through the first reduction gear plate 46; the second power output shaft 42 forms a transmission match with the waist and back massage component 3 through the second reduction gear plate 47.

[0058] Among them, the power supply 43 is rechargeable, and the maximum output voltage does not exceed 48V. Even if leakage occurs, it will not cause great harm to the user, ensuring the safety of the user's electricity use. If the head and neck massage component 2 and the waist and back massage component 3 run too fast, the user experience is poor and it will also cause certain harm to the user's body. Therefore, through the setting of the first reduction gear plate 46 and the second reduction gear plate 47, the transmission deceleration can be achieved, so that the head and neck massage component 2 and the waist and back massage component 3 can run at a speed more suitable for the human body.

[0059] 2. Head and neck massage assembly 2: includes a head and neck rotating disk 21, and a low massage block 22 and a high massage block 23 installed on the head and neck rotating disk 21. The head and neck rotating disk 21 forms a transmission match with the first reduction gear disk 46 through the first drive shaft 24.

[0060] The dual output motor 44 is started, and the power is transmitted to the head and neck rotating disk 21 after being decelerated by the first reduction gear disk 46, so that the low massage block 22 and the high massage block 23 on the head and neck rotating disk 21 rotate and continuously switch positions to achieve massage of the user's head and neck area. At the same time, due to the use of the low massage block 22 and the high massage block 23, the positions of the two are changed alternately, achieving a high and low switching massage effect, and the user experience is more comfortable.

[0061] III. Lumbar and dorsal massage assembly 3: It includes an eccentric swing block 31, a swing rod 32, a lumbar massage assembly 33, and a dorsal massage assembly 34; the eccentric swing block 31 is provided with a swing input shaft 311 and a swing output shaft 312. The eccentric swing block 31 forms a transmission fit with the second reduction gear disc 47 through the swing input shaft 311, and the eccentric swing block 31 forms a transmission fit with the swing rod 32 through the swing output shaft 312. Moreover, the swing input shaft 311 and the swing output shaft 312 are arranged non-coaxially, so that the swing rod 32 realizes the swing effect of an eccentric trajectory, improving the swing coverage area, and further making the massage area larger. The lumbar massage assembly 33 is arranged at the lower end of the swing rod 32, corresponding to the user's lumbar position; the dorsal massage assembly 34 is arranged at the upper end of the swing rod 32, corresponding to the user's dorsal position.

[0062] In the prior art examples 1 and 2, due to the relatively large body areas where the waist and back are located, there are certain massage blind spots between the waist and back regions. To solve the above defects, the adopted solution is: several transitional massage heads 35 are further provided on the swing rod 32. The transitional massage heads 35 are located between the lumbar massage assembly 33 and the dorsal massage assembly 34. Since the swing rod 32 is constantly moving, the transitional massage heads 35 will also constantly change their positions along with the swing rod 32, so that the massage area that the transitional massage heads 35 can cover is further increased, better eliminating the massage blind spots and enhancing the user experience.

[0063] To better constrain the movement trajectory of the swing rod 32, the further structural solution adopted is: an installation bracket 5 is provided in the second chamber 12, and the second reduction gear disc 47 is fixed on the installation bracket 5; among them, a guide rod 51 is further provided on the installation bracket 5, a limit trajectory groove 321 is opened on the swing rod 32, and the swing rod 32 extends into the guide rod 51.

[0064] Regarding the further solution of the lumbar and dorsal massage assembly 3 in this embodiment, the lumbar massage assembly 33 includes a lumbar massage bracket 331 rotatably connected to the swing rod 32, and lumbar massage heads 332 rotatably connected to the upper and lower ends of the lumbar massage bracket 331 respectively; the lumbar massage heads 332 can rotate relative to the lumbar massage bracket 331, the lumbar massage bracket 331 can rotate relative to the swing rod 32, and the swing rod 32 can swing by itself. The combination of the three can enable the lumbar massage heads 332 to provide a more three-dimensional movement trajectory, and can make the lumbar massage heads 332 better fit each person's back, with a wider adaptability.

[0065] On the other hand, the back massage component 34 includes a back massage bracket 341 and a plurality of back massage heads 342 distributed annularly on the back massage bracket 341, which can provide an annular massage effect to the back area of the user.

[0066] Embodiment 3

[0067] Based on the structure of any of the foregoing embodiments, this embodiment provides a safety structure measure, specifically: referring to Figure 1 , pressure sensors 6 are provided in both the first chamber 11 and the second chamber 12, and the pressure sensors 6 are communicatively connected to the control circuit board 45. Only when the pressure sensors 6 detect sufficient pressure and feed it back to the control circuit board 45 can the power be smoothly turned on and the drive mechanism 4 be activated to prevent accidental startup, especially to prevent the elderly, children, and pets from accidentally touching and starting, thus enhancing the safety of the cushion.

[0068] It should be noted that the other technical solutions of the present invention belong to the prior art, so they will not be elaborated here.

[0069] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as within the protection scope of the present invention.
